Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.
In chemical graph theory and in mathematical chemistry, a molecular graph or chemical graph is a representation of the structural formula of a chemical compound in terms of graph theory. A chemical graph is a labeled graph whose vertices correspond to the atoms of the compound and edges correspond to chemical bonds .
E)-Stilbene, commonly known as trans-stilbene, is an organic compound represented by the condensed structural formula C 6 H 5 CH=CHC 6 H 5. Classified as a diarylethene , it features a central ethylene moiety with one phenyl group substituent on each end of the carbon–carbon double bond .
These can be described by the condensed structural formulas and (). The third isomer of C 3 H 8 O {\displaystyle {\ce {C3H8O}}} is the ether methoxyethane (ethyl-methyl-ether; III ). Unlike the other two, it has the oxygen atom connected to two carbons, and all eight hydrogens bonded directly to carbons.

Propadiene (/ p r oʊ p ə ˈ d aɪ iː n /) or allene (/ ˈ æ l iː n /) is the organic compound with the formula H 2 C=C=CH 2. It is the simplest allene, i.e. a compound with two adjacent carbon double bonds. [3] As a constituent of MAPP gas, it has been used as a fuel for specialized welding.
Most properties listed in the literature refer to the racemic compound (an equimolar mixture of the two enantiomers). The boiling point of 89.7 °C is 0.3 °C higher than the value of 89.4 °C predicted by Wiener's formula, based on the structure of the molecule and the boiling point of n-heptane. [2] [3]
Methylpentene is an alkene with a molecular formula C 6 H 12.The prefix "methyl-" is derived from the fact that there is a methyl(CH 3) branch, the word root "-pent-" is derived from the fact that there are 5 carbon atoms in the parent chain, while the "-ene" suffix denotes that there is a double bond present, as per IUPAC nomenclature.
